How to use VPN on mobile devices?
We will look at those devices that have on Board the popular OS, such as iOS or Android.

Using VPN on smartphones or tablets is also quite simple, namely-through mobile applications. The problem is that some programs require root-rights, and this additional troubles, plus, the ability to turn the phone into a "brick". So look for those programs that do not require you to root. On Android, for example, it's OpenVPN, and on iOS it's Cloak. Also on the iPhone and iPad, you can use the free and proven Opera VPN for iOS. I myself sometimes use it, it works fine.
The download technology is very simple: download the app from the Play Market or AppStore, install it on your device. Next, activate the VPN, select the profile (from where, get the IP address), then, the connection is made and that's it. Now you walk on the Internet through a VPN, and what you will tell the application used.

Now you understand how the technology of VPN connections is implemented, and now your stay in the network will become more secure, anonymous, and most importantly-accessible and unlimited.
